WARP STOP-MOTION FOR LO OMS.

SPECIFICATION forming part of Letters Patent No. 673,818, dated May '7, 1901.

Application filed January 21, 1901. Serial No. 44,010. (No model.)

To all whom it may concern.- bars d and the detectors are herein shown Be it known that I, HENRY JONES, a citias arranged in two parallel banks or series zen of the United States, and a resident of in a manner well known to those skilled in Belton, county of Anderson, State of South the art, the detectors being normally 'inop 55 p Carolina, have invented an Improvement in erative by warp threads. I have herein WVarp Stop-Motions for Looms, of which the shown a feeler f to cooperate with each bank following description, in connection with the or series of detectors, the feelers being con accompanying drawing, isaspecification,like nected by arms f each with a rock-shaft f characters on the drawing representing like mounted in brackets F, secured to the loom 60 IO parts. side, one being herein shown. To transmit This invention has for its object the prorocking 'motion from one to the other rockduction of novel warp-stop-motion mechanshaft, I have herein shown them as provided ism particularly adapted for use in connecwith intermeshing segmental gears f One tion with looms for weaving, a feeler, which of the rock-shaftsf has fast upon it a rocker- 65 forms a part of the stop-motion, being viarm f to which is pivotally connected a link brated by or through the movement of the f, having at its lower end a longitudinal slot lay, and the operation of the stopping means f entered by a stud or pin a on a downfor the loom is also derived from the same wardly and rearwardly curved arm a, sesource. cured to one of the lay-swords, near the ful- 70 Various novel features of my invention crum A thereof.

If the will be manifest that the spring at such time dog is elevated into the path of the hunter on normally prevents any longitudinal movethe forward stroke of the lay, the rock-shaft ment of the link relatively to the lay-sword. it" will be turned to swing the knock-off arm As shown in the drawing, when the lay 5 in the direction of the arrow 5 to thereby removes back the arm ct moves into dotted-line lease the shipper-lever from its usual holdingposition and operates to draw down the link notch. against the pull of the spring 8X, thereby The warp stop motion mechanism comswinging the feelers outward and away from prises detectors cl, warp-receiving openings the detectors; but the forward end of the I00 d, and herein shown as also longitudinally rocker-arm a will not normally be elevated slotted at d to receive, support, and guide sufficiently to bring the dog k into the path of the bunter a As the lay comes forward the spring 5 acts to move the link f upward, as has been stated, the bottom of the slot f engaging the pin a and at such time the dog remains in inoperative position, provided the feeling movement of the feeler is not arrested.

Should one of the detectors d be released, as by failure or breakage of its warp-thread, it will arrest the feeling movement of the feeler on the beat up of the lay and the link f4 will operate to turn the rocker-arm a on its fulcrum 1, raising the end of the rockerarm beneath the dog k to place the latter in the path of the hunter, and as the lay comes forward the bunter will engage the dog and through the devices shown will release the shipper-lever and effect the operation of the .stopping means. Thus the vibration of the feeler is not only derived from the movement of. the lay-sword, but the actuation of the stopping means is also derived from the same source,and the connections between the feeler and lay-sword control the actuation of the stopping means.

When a feeler is arrested by a released detector, so that the upward or spring-impelled movement of the link f is prevented, the longitudinal slot f permits the necessary play of the pin or stud a? as the lay beats up, so that the arm a will be rocked and the detectors will not be crushed.

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1 In a loom, the lay and a lay-sword, a bunter, and a rocker-arm, both on the lay-sword, warp-stop-rfiotion mechanism, including a feeler and a rock-shaft on which it is mou nted,

an actuating-link operatively connected with the rock-shaft and lay-sword and pivotally attached to one end of the rocker-arm, a spring ei'asm tending to depress the other end of the rockerarm, and stopping mechanism, including a dog controlled as to its position by the rockerarm, arrest of the feeler acting through the link and said rocker-arm to move the dog into the path of the bunter.

2. In a loom, the lay and a lay-sword, a bunter thereon, warp-stop-motion mechanism, including a feeler, a link between it and the lay-sword and having a lost-motion connection with the latter, a spring tending to ele- 'vate the link and effect feeling movement of the feeler, its opposite stroke being effected by movement of the lay-sword, and stopping mechanism, including a dog controlled by the said connection, arrest of the feeler operating through said connection to move the dog into the path of the hunter.

3. In a loom, the lay and lay-sword, a bunter on the latter, operative on its forward stroke, warp-stop-motion mechanism, including a feeler, a spring-controlled rocker-arm on the lay-sword, a link connecting the latter and the feeler and pivotally connected withthe rocker-arm, and stopping mechanism, including a dog controlled as to its position by the rocker-arm, backward movement of the lay-sword acting through the link to swing the feeler in one direction, the arrest of the opposite, or feeling movement of the feeler, acting through said link to rock the rocker-arm and move the dog into position to be engaged by the hunter on the forward stroke of the lay-sword.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY JONES.
